Kelly Osbourne is having a rehab redux.
The erstwhile reality television icon, 24, checked into Oregon's Hazelden Alcohol and Drug rehabilitation center on Wednesday. She logged time in similar Los Angeles-area treatment programs in Promises, when she was 18, and Las Encinas, at 20.
"Yeah, Kelly's in rehab," her mother, Sharon Osbourne, told Radar Online. "What else can we say? She knew that it was the right thing to do at this point and we're proud that she did it. The family is all standing behind her. Kelly knew that she needed help and she's getting it.
The starlet, who's engaged to Luke Worrall, is expected to remain in the facility for at least 30 days. The exact nature of her problem has yet to be revealed.
"Kelly will let you know herself when she gets out," the Charm School dean promised.
The addiction admission comes just days after the sometimes-singer was arrested for assault for allegedly slapping a journalist in August 2008.
The famous family, including Ozzy Osbourne, is in the middle of shooting a television variety show for Fox, Osbournes Reloaded.
"She'd been working right up until she went in," her mother said, getting emotional. "This is one of the absolute worst things that a parent can face, for their child to go through rehab. And not once, but twice."
